Description
Technical field
The invention belongs to percolate field of garbage disposal, is related to a kind of method of safe utilization percolate treatment plant biogas.
Background technology
The biogas main component that landfill leachate produces is methane, and directly emptying will aggravate Global Greenhouse Effect and cause
Environmental pollution, domestic general processing method is directly burnt using torch, causes the profligacy of resource.Biogas is utilized in conveying
During without effective and safe safeguard.Since methane has explosion danger, once the problem that leaks air, will cause around to exist
Severe compromise.
The biogas that landfill leachate produces is delivered to torch by wind turbine and burns, and the high-temperature flue gas of generation is directly discharged into
Air.Torch is made of flare tip, cylinder, burning torch, spark arrester, pylon etc., after biogas is delivered to torch, by automatic ignition control
Cabinet processed automatically controls carry out ignition.
Directly burnt using torch, cause the profligacy of resource, cause environmental pollution, and biogas was utilized in conveying
Without effective and safe safeguard in journey, causing surrounding environment, there are severe compromise.
The content of the invention
In view of this, it is an object of the invention to provide a kind of method of safe utilization percolate treatment plant biogas.
To reach above-mentioned purpose, the present invention provides following technical solution：
A kind of method of safe utilization percolate treatment plant biogas, connects respectively again after UASB ponds are connected freq uency conversion supercharging wind turbine
Connect incinerator and torch, the pumping position negative pressure value in UASB ponds and freq uency conversion supercharging wind turbine by DCS control system chain controls, when
When the change of biogas rate of air sucked in required exceeds burner load variations scope, start torch；
Main pipe, freq uency conversion supercharging fan outlet, incinerator entrance is evacuated before each bleed off passage, freq uency conversion supercharging wind turbine to be pressed
Power detects, and when a certain position leaks air, the control of DCS control systems produces pressure alarm, performs freq uency conversion supercharging fan parking and moves
Make；
Carried out before incinerator and torch biogas pressure detecting, methane content detection, oxygen content Concentration Testing, in case of
Abnormal, instrument sends overload alarm, and DCS control systems are immediately performed shutdown procedure.
Further, before freq uency conversion supercharging, desulfurization process first is carried out to biogas, by H2S contents are down to 200mg/m3Below.
Further, by freq uency conversion supercharging wind turbine voltage stabilizing, by pressure control between 8~20kPa.
Further, purified treatment is carried out to the biogas after freq uency conversion supercharging wind turbine.
Further, the purified treatment includes dehydration and dedusting.
The beneficial effects of the present invention are：The biogas that landfill leachate produces is delivered to the incinerator in power plant by the present invention
In, thermal power generation is carried out by burner combustion.Achievable biogas makes full use of safely.The present invention can carry out system and monitor,
Safeguards system pressure flow is stablized, once leaking air, can find and adopt an effective measure rapidly, prevent accident, ensures
System normal safe operation.
Brief description of the drawings
In order to make the purpose of the present invention, technical solution and beneficial effect clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is the connection relationship diagram of the method for the present invention.
Embodiment
Below in conjunction with attached drawing, the preferred embodiment of the present invention is described in detail.
The present embodiment will illustrate this method with reference to Fig. 1, a kind of safe utilization percolate treatment plant biogas of the present invention
Method, UASB ponds 1 are connected and connect incinerator 3 and torch 4, the pumping position in UASB ponds 1 after freq uency conversion supercharging wind turbine 2 respectively again
Negative pressure value, by 5 chain control of DCS control systems, exceeds burner load with freq uency conversion supercharging wind turbine 2 when biogas rate of air sucked in required changes
During excursion, then valve 11 is opened, start torch 4；To ensure system safe and stable operation.
Main pipe, the outlet of freq uency conversion supercharging wind turbine 2, burning are evacuated before each bleed off passage, freq uency conversion supercharging wind turbine 2 in UASB ponds 1
The entrance of stove 3 carries out pressure detecting, is equipped with pressure sensor 6, and pressure sensor 6 is connected to DCS control systems 5, when
A certain position leaks air, and DCS control systems 5 control flammable gas alarm to produce pressure alarm, performs freq uency conversion supercharging wind turbine 2
Shutdown action；Service personnel carries out inspection operation.
Carried out before incinerator 3 and torch 4 biogas pressure detecting, methane content detection, oxygen content Concentration Testing, point
Pressure sensor 6 and methane content detector 7, oxygen content concentration detector 8, pressure sensor 6 and methane content are not provided with
Detector 7, oxygen content concentration detector 8 are connected to DCS control systems 5, and in case of abnormal, instrument sends overload alarm, DCS controls
System 5 is immediately performed shutdown procedure.
As further improvement of this embodiment, the torch 4 uses and diffuses igniter.Ensure that garbage power system exists
Drop a hint and timely, safe and reliable can be burnt in burner caused by normal condition or accident condition, meet heat
The environmental requirement such as radiation and noxious gas emission concentration.In the present embodiment, before freq uency conversion supercharging, desulfurizing tower 9 first is passed through to biogas
Desulfurization process is carried out, by H2S contents are down to 200mg/m3Below.By 2 voltage stabilizing of freq uency conversion supercharging wind turbine, by pressure control 8~
Between 20kPa.Then purified treatment is carried out with purifier 10 to the biogas after freq uency conversion supercharging wind turbine.This technical solution was both realized
Biogas safe utilization, and biogas utilization value can be improved, solve environment and peace caused by the single possibility of biogas utilization approach
Full problem.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
